DUNCAN IIIORTOLT, OF VANCOUVER, BRITISH COLUMBIA, CANADA.

COIWBINATION ENGINE Application filed September To all whom it mayconcern:

Be it known that 1, Duncan Morrron, a citizen of the Dominion of Canada,and resident of Vancouver, in the county of Vancouver and Province ofBritish Columbia,

Dominion of Canada, have invented certain new and useful Improvements inCombination Engine and Pump Structures, of which the following is aspecification.

This invention has relation to certain new theoperative parts of thestructure or other injury thereto which would interfere with properoperation of the mechanism.

The invention consists in the novel construction, combination andarrangement of cooperating elements as hereinafter more specifically setforth, claimed and shown in the accompanying drawings forminga part ofthe present application, in which:

Fig.1 is a side elevation of. the complete structure.

2 is a plan view thereof.

Fig. 3 is an end'clevation, looking at the pump end of thestructure.

Fig. 4 is vertical longitudinal section through the complete structure,with parts in elevation.

Fig. 5 is an enlarged end elevation of the pump with the end coverremoved.

6 is anenlarged section through the engine cylinder head, showing theintake and exhaust valves and also the water pocket of the enginecylinder head extending between the valves.

Referring more in detail to the drawings, in which similar referencecharacters designate corresponding parts throughout the several views,10 designates the supporting base which is common to both the engine andpump, as shown in Figs. 1, 2 and. 4. At one end, the supporting base 10has an upstanding p ortion ll formed to support the enginecrank casii 12having bearings 13 atits opposite Sl-f for thomain or crank:

primary object the provision of acombina- AND YUM]? STRUCTURE.

5, 1922. Serial No. 586,296;

shaft 14, as shown clearly in Fig. 4. The bottom 15 of the engine crankcasing 12 depends into the upstanding portion 11 of the supporting base10 and bottom 15 has ,a further depress-ed. portion 16 opposite thecrank portion 17 of the main or crank shaft 14. This may also be clearlyseen by refer ring to Fig. 1. A suitable drain'cock 18 is secured in thelower portion of the engine crank casing 1.2 for draining the latterwhen desired. Agear wheel 19 is carried on the main or crank shaft 14within the engine crank casing 12, the purpose of which will presentlyappear.

By referring to Fig. 1, it will be seen that the engine crank casing 12is preferably constructed of upper and lower sections which cut throughthe bearings 13, the sections being suitably connected by clamping bolts20. It will also be seen by referring to Fig. 4 that the engine crankcasing 12 hasan opening 21 in its upper side over which the enginecylinder 22 is mounted, said engine cylinder 22 carrying an out-turnedflange 23 at its lower end, through which the bolts 24 are extended forclamping the engine cylinder 22 in position. I

Mounted on an extended end of the main or crank shaft 14 is the balancewheel 25 with which is engaged a stop collar 26 located on the main orcrank shaft 14, inwardly of the balance wheel 25. A suitable lock nut 27is threaded on the outer extremity 28 of the main or crank shaft 14 toprevent the balance wheel 25 from working off of the main or crank shaft14.

Tire engine piston 29 working within the engine cylinder 22 is mountedon the upper end of thepiston rod 30 by suitable connection 31. Thepiston rod 80 has its lower end 32 suitably mounted on the crank portion17 of the main or crank shaft 14, as shown in Fig. 4. Itis tobeunderstood that the engine piston 29 and the piston rod 30 are both ofconventional form and therefore need no further detailed description.

The engine cylinder 22 has an annular flange 33 extending around theexterior thereof near thelower end of said engine cylinder 22. Thesleeve 34 forming the water jacket for the engine cylinder 22 ispositioned around the latter and in spaced relation thereto, the lowerend of the sleeve 34 joining the annular flange 33. a i The sleeve 34 isof sufficient length to extend practically t0 the top of the enginecylinder 22, as shown in Fig. 4. The sleeve 34 has a water inlet opemng35 near its lower end, the purpose of which will presently be apparent.

The removable cylinder head 36 for the outer open end of the enginecylinder 22 is removably positioned on the upper end of the enginecylinder 22 and the water jacket forming sleeve 34, as also shown inFig. 4 with the central portion 37 of the removable cylinder head 36depending into the engine cylinder 22. The removable cylinder head 36 ishollow, thereby providing the water pocket 38 which also hascommunication with the water pocket 39 formed between the enginecylinder 22 and the water jacket forming sleeve 34 spaced around saidengine cylinder 22. It will be understood that the removable cylinderhead 36 may be securely fastened in position in any suitable and wellknown manner.

The removable cylinder head 36 has a threaded water outlet port 40 atone side for the water pocket 38. as shown in Fig. 4 and the purpose ofwhich will presently appear. The removable cylinder head 36 also has afuel inlet port 41 with an interiorly threaded outer end 42 while thevalve seat 43 is formed at the inner end of the fuel inlet port 41 forthe inlet valve 44. The inlet valve 44 is mounted on the lower end ofthe valve stem 45 which reciprocates vertically through the removablecylinder head 36, as shown clearly in Fig. 6. A spring 46 is positionedaround the outer or extended end of the valve stem 45 with one end ofthe spring bearing against the spring seat 47 formed on the upper faceof the removable cylinder head 36. The other end of the spring 46 bearsagainst the bearing washer 48 held in adjusted position on the upper endof the valve stem 45 by the ad" justable nut 49 threaded thereon.

The exhaust port 50 is also formed in the removable cylinder head 36with the outer end 51 of the exhaust port 50 interiorly threaded, whilethe valve seat is formed at the inner end of the exhaust port 50. Theexhaust valve 53 normally engages the valve seat 52 and thereby closesthe exhaust port 50. The valve stem 54 extends upwardly from the exhaustvalve 53 and reciprocates through the removable cylinder head 36. Theexpansion spring is extended around the valve stem 54 with one end ofthe expansion spring 55 engaging the spring seat 56 formed on the outerface of the removable cylinder head 36. around the valve stem 54. Theother end of the expansion spring 55 bears against the bearing washer5'7 mounted on the valve stem 54 and limited in its outward movement onthe valve stem 54. by the stop pin 58 extended through the valve stem54. i

It will be readily seen by referring to Fig. 6 that the water pocket 38in the removable cyhnder head 36 extends between the fuel inlet port 41and the exhaust port 50. It will also be seen by referring to Figs. 1, 2and 4 that a spark plug 59 of conventional form is mounted in a suitableopening 60 provided for this purpose in the removable cylinder head 36and extending through the latter. The upper extremity of the valve stem54 for the exhaust valve 53 is suitably connected with one end of theexhaust valve operating rock arm 61, which latter is mountedintermediate its ends on the pivot member 62. the opposite or outer endof the exhaust valve operating rock arm 61 being moimted on the pivotmember 63. which latter also extends through the forked upper end 64 ofthe member 65 carried on the upper end of the reciprocating rod 6. Theouter end of the exhaust valve operating rock arm 61 is inclosed in theforked upper end 64 of the member 65, as will be clearly understood byreferring to the drawings, particularly Figs. 1 to 4 inclusive. A cotterpin 67 or the like is extended through one end of the pivot member 63 toretain the latter in position.

The reciprocating rod 66 extends through the upper portion of thebearing casing 68 and has its lower end 69 resting upon the cam member 7O on the cam shaft 71, which latter is rotatably mounted in the bearingcasing 68 and corresponding bearing members 72 provided on the portionof the upper side of the engine crank casing 12 on which the bearingcasing 68 is supported. A cushioning spring 73 is positioned around thereciprocating rod 66 with one end engaging with the bearing casing 68,while the upper end of the cushioning spring 73 engages the bearingwasher 74 positionedon the reciprocating rod 66. Upward movement of thebearing washer 7 4 on the reciprocating rod 66 is prevented by the stoppin 7 5 extended through the reciprocating rod 66. The pivot member 62is mounted in the upper end of the inclined supporting arms 76 of theplate 77 which is mounted on the upper face of the removable cylinderhead 36 near one edge thereof. by the bolts 78 or other suitable means.The bolts 78, together with similar and additional bolts 78 shown inFig. 2. serve as the means to secure the removable cylinder head 36 inposition.

It will be evident that as the cam shaft 71 is rotated, the cam member 70 will, with each revolution of the cam shaft 71, force upwardly thereciprocating rod 66 and thereby operate the exhaust valve operatingrock arm 61 to open the exhaust valve 53, against the action of theexpansion spring 55. As the expansion spring 55 is P ed o Operate e clse the e haust '19 and thereby assures proper operation of theeam shaft71' by'the main or crank shaft- 14. The gear wheel 79 is partiallyenclosed by the bearing casing68, whlle the remainder of the gear wheel79 projectsinto the engine crank casing 12.

- Connected wit-h the cam shaft 71 through the medium of the clutch 80,'is the magneto shaft81. The magneto 82; which is shown conventionallyin the drawings, is supportc d on the supportingmember 83 carried on thes'upportingbase 10,-abo'ut centrally of the pump supporting endof saidsupporting base 10. Thesupporting member 83 issecured to the upstandingflanges-84c of-'the pump supporting end of the supporting base 10 bybolt-s 8501' other suitable connecting members.

Tank supporting brackets 86 are mountedon the supporting base 10 atopposite sides of the pump supportingend thereof. The tank supportingbrackets 86 areofsubsta ntially invertedU shapedform and have longand'sho'rt legs, the long legs being mounted on the bottom of thesupporting base 10-near the corners thereon-while the short legs aremounted on the upstanding portion 11 0f the supporting base 10,"at thecorners of the engine era-nkeasing 12. The tank supportingbrackets 86-have transverse bracingmembers 87 connecting the lower ends of theshortlegs with the long legs of said tank supporting brackets 86 and alsohave arcuate transverse bracing members 88 connecting the legs near theupper ends thereof.

The main portions ofthe upper ends of 1 tions with the uppermost centralportions of the arcuate transverse bracing members 88, as shown at 89,these upper ends of the tank supporting "brackets 86 therebyconstituting lower arcuate supporting bearings 90 for the end portionsof the fueltank 91. Upper arcuate supporting bearings 92 are extendedover the end portions of the fuel tank 1 91 and? provided without-turned ends 93 secured upon the upper ends of the tank supportingbrackets 86 to either side of the lower arcuate supporting bearings 90,by suitable securing members 94. as shown clearly in Figs. 1 and 1. Thefuel tank 91 has a filling opening normally closed by the .plug 95 and afuel supply pipe 96 extends pressed outwardly from the same.

from the fuel tank 91 to supply fuel to the carburetor 123 connectingwith the intake pipe 980]. the engine.

It will be understood that the intake pipe 98 issecured in theinteriorlythreaded outer W end 42 of the fuel inlet port 41 in the removablecylinder head 36. It will also heapparent that the fuel passing throughthe fuel supply pipe 90 from the fuel tank 91 may be readily controlledby means of the valve 97secured in said fuelv supply pipe 90-near itspoint of connection with the fuel tank 91. It is also to be understoodthat suitable connections, not shown. are made between the spark plug 59and the magneto 82 so as to assure proper operation of the spark plug 59during operation of the engine. The engine exhaust pipe 99 projects fromthe exhaust port 50, as shown in Figs. 1 and 2, one end of the engineexhaust pipe 99 being secured-in the threaded outer end 51 of saidexhaust port 50.

The pump operating shaft 100 is in alignment with the main or crankshaft 14 and connected for operation with the latter by means of aclutch 101. The pump operating shaft 100 extends through the lowerportion of the pump cylinder 102 and through the removable pumpeylindi-ar head 103 for the outer end ofthepump cylinder 102. A suitablebushing and sleeve 101 is carried by the pump'eylinder 102 andmountedaround the pump operating shaft 100 to reduce leakage of the pump to theminimum. The pump cylinder 102 is mounted on the upstanding portion 105of the supporting base 10, at the end opposite that end supporting theengine. This upstanding portion 105 is of proper size 'andwshape toproperly support the pump, as will be clearly apparent by referring tothe drawings.

The removable pump cyliiiderhead 103 is secured in position by the bolts100 or o her suitable means. A second pump shaft 107- is rotatablymounted in the upper por ion of the pump cylinder 102 with one end ofthe second pump shaft 107 rotating in the bearing pocket 108 providedtherefor in the closed head of the pump cylinder 102 and extendedoutwardly from the same. The opposite end of thesecond pump shaft 107rotates in the bearing pocket 109 forn'ied in the removable pumpcylinder head 103 and A cox. responding bearing pocket 110 is alsoformed in the lower portion of the removable pump cylinder head 103 forthe outer free extremity of the pump operatin shaft 100. The *pumpcylinder 102 is provided with a water inlet pipe 111 located centrallyat one side, while a similarly located water discharge pipe 112 pro ectsfrom the upper side of the pump cylinder 102.

Mounted on the pump operatingshaft 100*andthe second pump shaft 107are'the cylindrical rotatable pump members 113 and 11 1, respectively,which have spaced peripheral teeth 115 which are adapted to interlock atthe center of the pump cylinder 102 and thereby cause rotation of thecylindrical rotatable pump members 113 and 114i in reversed directionsas the pump operating shaft 100 rotates. Each of the cylindricalrotatable pump members 113 and 11 1 works in a pocket just slightlylarger than itself and the peripheral teeth 115 extend completely acrossthe peripheral faces of. the cylindrical rotatable pump members 113 and11 1, thereby causing these peripheral teeth 115 to catch the waterentering the pump cylinder 102 by way of the water inlet pipe 111 andcarry the water around the cylindrical rotatable pump members 113 and114 in the pockets between the peripheral teeth 115 thereof anddischarge the water from the pump cylinder 102 by way or the waterdischarge pipe 112. This will be clearly understood by parties familiarwith this type of pump.

As the pump is operated with the engine, the water will be constantlydischarged from the water discharge pipe 112. A portion of the waterpassing through the pump will also be forced through the waterconducting pipe 116 into the water pocket 39. One end of the waterconducting pipe 116 connects wit-h the discharge side of the pumpcylinder 102, while the other end connects with the water inlet opening35 of the water pocket 39. After the water has passed through the waterpockets 39 and 38, it discharges by way of the water discharge pipe 117projecting from the pipe connection 118 secured in the threaded wateroutletport 40, as will be understood by referring to Figs. 1 2 and 4.

A conventional form of lubricant cup 119 is mounted on the removablecylinder head 36. The lubricant employed in the engine crank casing 12may be readily supplied thereto through the lubricant port 120 which isnormally closed by the plug 121. as shown in Figs. 1, 2 and Anappropriate lubricant cup 122 is mounted on the pump cylinder 102 forsupplying the necessary lubricant to the pump parts. It will also beevident that any other appropriate means may be employed forautomatically lubrieating other parts of the structure, as desired.

It. is believed the complete construction and operation may now bereadily understood from the foregoing paragraphs taken in connectionwith the accompanying drawings without further detailed description. Itmay be briefly stated however. that the engine and pump are driventogether by the main or crank shaft 1 1 and the pump operating shaft100, arranged in alignment and connected for operation together by theclutch 101. Furthermore, a portion of the water forced through the pumpcylinder 102 is employed for closing the engine cylinder 22 and theremovable cylinder head 36 as the engine and pump operate, therebyincreasing the ethciency of the structure or unit. The cam shaft 71coupling with the magneto shaft 81 in alignment therewith and bothshafts being controlled directly by the main or crank shaft 14, assuresproper timing and operation of the exhaust valve 53 and the sparking orignition mechanism of which the spark plug 59 forms a part.
